Class Information
Number: 137/614.03
Name: Fluid handling > Systems > Flow path with serial valves and/or closures > Separable flow path section, valve or closure in each > Each valve and/or closure operated by coupling motion > Linear motion of flow path sections operates both
Description: Systems in which the joining or disconnecting includes a linear component of motion of the flow path sections with respect to each other, which linear component results in the operation of both valves, flow controllers or closures.
